I've been banned as Everyman, Doofus, Snafu, and Kackle. It's because I was the first consistent Google critic (if you don't count marketers who complained about their rankings every month), and Brett is a Google fanboy. I haven't been around much since the period from 2000-2003, when I was most active. I was very interested in Google and still am, but I've never been interested in ecommerce or ads.
Even today, you cannot spell "#*$!" (by the way, that was supposed to be #*$!) on this site, even though it handles over 300,000 searches a day now and has existed since 2003.
